Definitions

  • the present invention relates generally to communication technology.
  • the invention relates to a technique for providing electronic messages within a communication network.
  • Electronic messages such as electronic mail messages (or emails) are most commonly used these days for exchanging information with one another.
  • emails are often used in connection with business activities, such as advertising, sales activities, invoicing, and so on.
  • emails can be classified depending on their content and/or depending on who is generating the emails and for whom the generated emails are intended. For instance, there are known emails that are generated individually by people at a sender device and intended for other people at a recipient device.
  • emails that are generated in an automated way by a corresponding application/software related to a business process at the sender device and intended for specific people or specific application(s) related to specific business process(es) at the recipient device.
  • automated emails are transactional emails that are generated and sent in response to an action/request of a user or an application (process) at the recipient device (for instance, a password reset email in response to a password reset request, an account creation email in response to an account creation request, an order confirmation email in response to an order, a shipping confirmation email in response to a shipping order, emails related to invoices in response to a purchase, etc.).
  • Other examples for automated emails are marketing emails that comprise content intended for a large number of recipient devices at the same time. Examples for such marketing emails are newsletters, limited time offers, sales campaigns, vouchers, and so on. The content of such automated emails is typically related to a commercial purpose.
  • a method of providing electronic messages is provided, wherein the method is performed by a messaging server and comprises the following steps: receiving an electronic message from a first communication entity; determining whether the electronic message is intended for a user or a specific application at a second communication entity; if the electronic message is found to be intended for a specific application at the second communication entity, checking whether the electronic message can be processed by the application at the second communication entity; and providing the electronic message to the second communication entity if it is found that the electronic message can be processed by the application at the second communication entity.
  • the term "electronic message” may encompass any type of message that can be exchanged between two or more electronic communication entities. More specifically, the electronic message may be an automated electronic message generated by a corresponding application or software tool at the first communication entity and intended for a user and/or an application or software tool at the second communication entity (for instance, an application related to a business process, such as an invoice processing application or order processing application).
  • the electronic message according to the invention may be an electronic mail message (in short email), an instant message, an EDI message (i.e., a message generated in accordance with the UN/EDIFACT standard) or any other type of electronic message.
  • electronic message does not only refer to a single electronic message (e.g., a single email), but also encompasses a plurality (i.e., a large number) of electronic messages (e.g., emails) that can be generated by a corresponding application (or software tool) at the first communication entity in an automated way.
  • the first communication entity may be a (distributed) computer system, a computer terminal or any other message sender device configured to generate and send electronic messages automatically and/or upon user input, such as a smartphone, a tablet, a personal computer and/or any other private or corporate computer device.
  • the second communication entity may be a (distributed) computer system (e.g., a company computer system), a computer terminal or any other message receiving device configured to receive and process electronic messages automatically and/or upon user input, such as a smartphone, a tablet, a personal computer and/or any other private or corporate computer device.
  • both communication entities may be electronic communication entities, wherein the first communication entity may act as message sending device and the second communication entity may act as message receiving device.
  • the first communication entity is also referred to as message sending device
  • the second communication entity is also referred to as message receiving device.
  • a software tool or software module i.e., software routines
  • a software tool or software module capable of processing that specific type of content may be provided at the second communication entity.
  • message content related to business processes such as quotations, orders, invoices etc., should be provided to corresponding applications at the second communication entity capable of processing that specific content in a desired way.
  • the message received at the messaging server may be a message intended for a specific user or a specific application at the second communication entity.
  • the step of determining whether the electronic message is intended for a specific user or a specific application at the second communication entity may comprise the sub-steps of analysing the electronic message received from the first communication entity, and classifying, based on the analysis result, the electronic message as a message intended for a user or as a message intended for a specific application at the second communication entity.
  • This analysis of the electronic message may comprise an analysis of the header information of the received electronic message, the content of the electronic message and/or the attachment(s) of the electronic message.
  • the analysis of the message header information may comprise an analysis of the message address(es) of the message sending device (the first communication entity) and/or the message receiving device (the second communication entity). For instance, it may be analysed whether the message address(es) comprise(s) an address portion which can be associated with a specific name of a user or a specific application at the message receiving device.
  • the analysis of the message body may comprise determining the type of content (for instance, whether the content relates to specific business processes, such as a quotation, order, invoice, etc.,) and/or the format of the content (for instance, whether the content is provided in the form of text, graphics and/or lists) in the message body.
  • the analysis of the message body may further comprise a search for one or more specific features in the content of the body (such as, an order number, invoice number, shipping number, etc.) that can be associated with a specific business process and therefore with a specific application capable of processing such content.
  • the attachment may be additionally analysed.
  • the format of the attachment is determined by analysing the file name and/or file extension of the attachment.
  • the analysis of the attachment may further comprise determining the type of content in the attachment (e.g., whether the content relates to a specific business process) and/or searching for one or more specific features (such as, an order number, invoice number, shipping number, etc.) in the content of the attachment that can be associated with a specific business process and therefore with a specific application capable of processing such content.
  • the message may be classified as a message intended for a user if the above-described analysis leads to the result that the message may comprise a content related to a specific user. Otherwise, the message may be classified as a message intended for a specific application if the above-described analysis leads to the result that the message may comprise a content related to a specific business process that can be processed by a specific application in an automated way.
  • the method may further check whether the message or message content is sufficiently compatible with that specific message processing application. Sufficiently compatible with the intended message processing application may mean that the message can be processed correctly by the application, i.e., the application will not be disturbed or crashed when trying to process the message (message content).
  • This compatibility check may comprise a check whether the format of the message (e.g., email message, EDIFACT message, etc.), the format of an attachment, if any, and/or the type of content of the message and/or attachment, if any, is compatible with the processing requirements of the application for which the message is intended.
  • the message may be pre-processed by the messaging server in such a way that the electronic message becomes processable by the application at the second communication entity.
  • This pre-processing of the electronic message may comprise converting the electronic message and/or the attachment of the electronic message into an electronic message having a message format and/or attachment format that can be processed by the application.
  • the pre-processing of the electronic message may comprise converting the content of the electronic message and/or attachment of the electronic message into a least one data object that can be easily processed by the application.
  • a data object for instance, JSON data object
  • the above-described pre-processing of the electronic message at the messaging server may not be limited to messages which have been found to be not sufficiently compatible with a message processing application for which the message is intended.
  • the pre-processing may be performed for any message received by the messaging server with the purpose to make the content of the message more easily accessible to the message processing application.
  • the step of providing the electronic message to the second communication entity may comprise providing the received electronic message and/or the pre-processed electronic message to the message processing application for which the message is intended. More specifically, the electronic message is provided to the message processing application after the above-described determining step has revealed that the electronic message is intended for that specific application. Moreover, the message may only be provided to the application if the above-described message checking step has revealed that the electronic message can be processed by that application. If the message checking step has revealed that the received message cannot be processed correctly by the message processing application, the pre-processed message is provided to the application instead. Alternatively, the at least one data object comprising the content of the received electronic message may be provided to the message processing application.
  • the step of providing the electronic message may further comprise providing the electronic message to a user at the second communication entity if the above-described determining step has revealed that the electronic message is intended for a user.
  • the electronic message may be provided by pushing the electronic message and/or the pre-processed electronic message to the second communication entity.
  • the messaging server implements a Push scheme (e.g., SMTP-Push; REST-Push) for providing the electronic message to the application.
  • the electronic message may be retrieved by the second communication entity from the messaging server.
  • the messaging server implements a Pull scheme (e.g., POP-Pull) for providing the electronic message to the application.
  • the method may comprise storing the electronic message and/or pre-processed electronic message at the server for a predetermined period of time.
  • the method may further comprise monitoring the sending status of the electronic messages. For instance, it may be monitored whether electronic messages are pulled by the second communication entity within a specific period of time. If the electronic messages are not pulled within that specific period of time, a notification message may be sent to the second communication entity.
  • the method may comprise subjecting the incoming electronic message to an antivirus security check.
  • an antivirus security check may comprise a virus signature check, sand boxing or any other type of malicious behaviour check.
  • the antivirus check may be performed by the messaging server.
  • the electronic message may be blocked and/or quarantined by the messaging server.

  • the determining unit 130 is designed to determine whether an incoming electronic message 11 is intended for a specific user or a specific application at the second communication entity 20. In case the incoming electronic message 11 is found to be a message for an application, it is determined for which application at the second communication entity 20 the message is intended. Accordingly, each incoming message at the messaging server 100 is classified as a user message or a message to be processed by a specific application at the second communication entity 20. This classification of the incoming electronic message 11 is based on a corresponding analysis of the message content (i.e., type and/or format of the message content), message header information, and/or message attachment.

It is also conceivable that the pre-processing unit 150 generates a data object based on the content of the electronic message 11. The data object may then be provided to the application for further processing instead of the original electronic message 11.
  • the messaging server 100 does not only route messages to the appropriate application at the second communication entity 20, but may also pre-process the received electronic message 11 in such a way that the content can be easily processed at the second communication entity.

  • the message 11 may be an electronic mail message (email), an EDIFACT message or a message according to another messaging format. The present invention does not depend on the specific format of the message 11.
  • the messaging server 100 determines whether the message 11 received from the first communication entity 10 is intended for a user or an application at the second communication entity 20.
  • This determining step is performed by the determining unit 130 of the messaging server 100.
  • the determining step is based on an analysis of the message header, message body and/or message attachment depending on whether the received message contains such an attachment.
  • the message addresses of the first communication entity 10 (i.e., the message sending device) and the second communication entity 20 may contain features that are indicative of a specific user or a specific application at the second communication entity 20. Additionally, or alternatively, the content of the electronic message 11 is further analysed.
  • This analysis may comprise an analysis of the type of content (for instance, whether the content comprises information related to an invoice, an order, a quotation, or personal information related to a user) and/or the structure (format) of the content (for instance, whether the content comprises information in the form of text, graphics and/or tables).
  • the electronic message 11 is classified by the determining unit 130 as a message intended for a user if the analysis of the message 11 reveals that the message comprises a content related to a specific user.
  • the electronic message 11 is classified as a message intended for an application at the second communication entity 20 if the analysis of the message 11 reveals that it comprises a content that can be processed by a specific application at the second communication entity 20.
  • the messaging server 100 further checks whether the electronic message 11 can be processed by that application at the second communication entity 20.
  • This checking of the electronic message 11 is performed by the checking unit 140 of the messaging server 100 and may comprise a compatibility check of the message 11 with the application for which the message 11 is intended.
  • This compatibility check may comprise a check whether the format of the message 11 (email message, EDIFACT message, etc.), the format of an attachment, if any, and/or the type of content of the message and/or attachment, if any, is compatible with the processing requirements of the application for which the message 11 is intended.
  • the messaging server 100 may directly provide the message 11 to that specific application at the second communication entity 20 (see 'Yes' branch in Figure 3 ).
  • the electronic message 11 may be provided to the pre-processing unit 150 for pre-processing (see method step S370 which is an optional method step indicated by a dashed line in Figure 3 ).
  • the pre-processing of the electronic message 11 may comprise a conversion of the electronic message and/or the attachment of the electronic message (provided that the electronic message comprises such an attachment) into an electronic message 11a having a message format and/or attachment format that can be easily processed (or interpreted) by the application.
  • the pre-processing may comprise a generation of a data object (e.g., a JSON data object) comprising the content (or relevant parts of the content) of the electronic message 11 and/or the attachment of the electronic message 11 and providing that data object to the application for further content processing.

  • the messaging server 100 provides (via the second communication module 120) the electronic message 11 and/or the pre-processed electronic message 11a to the second communication entity 20. That is, if the message 11 is classified as message intended for a user, the message is directly provided to the user (a corresponding mailbox associated with the user) at the second communication entity 20. If the electronic message 11 is classified as message intended for a specific application, the electronic message 11 itself or the associated pre-processed electronic message 11a is provided to that specific application at the second communication entity 20.
  • message 11 received at the messaging server 100 may comprise different types of content which may be related to different types of business processes and which may be processed in an automated way by different applications (software tools) at the second communication entity 20. Accordingly, the step of providing the electronic message 11 and/or pre-processed electronic message 11a to the second communication entity may involve a content-specific provisioning of the electronic message 11 to that application at the second communication entity, which is able to process the content in the electronic message 11 in a desired way.

  • a pull scheme that is, the message 11 and/or pre-processed electronic message 11a is retrieved from the messaging server 100 by the second communication entity 20
  • the above-described technique for providing electronic messages has many advantages over conventional techniques. For instance, messages having a content that is intended for specific applications for automated message processing is selectively routed to those applications which are able to process the content of the messages in an appropriate way. Further, by checking the content and format of the electronic messages it can be avoided that messages are provided to wrong applications or applications that are not able to (fully) process the message content. Moreover, if it is found that a message is not processable by an application for which the message is intended, the message will be routed to a backup analyser at the second communication entity for review. Hence, the present technique avoids that message content gets lost or message processing applications are crashed during automated message processing.
